which one would pull more air?

Recommended Posts

Posted · Original PosterOP

i'm going to buy a case fan for the pc, and there are two options, one is 2500rpm 92mm, and one of them is 1500rpm 120mm, which one of them would cool the pc better? i don't care about the noise it makes.

What fans exactly? These parameters might not be enough to determine the air volume.

Nobody can tell which is better.

It depends on the fan blades, how they're shaped, and how much the fan is obstructed by the grill or mesh

Some are more tuned for static pressure (for use with radiators and so on) and some are more  optimized for air flow (mounting on cases)

Ideally, you look up the datasheet of the fan and you see there the CFM (cubic feet per minute, amount of airflow). For moving air in case, you care less about air pressure which is listed in mm H20 or something like that.

 

Usually bigger diameters means less noise, but anything else depends on factors mentioned above.

maybe tell us your price range and we may be able to help you

System specs and temps?? How's the case airflow set up?

Where's the fan being used and which fans are you looking at?

ok, so i have an itx computer, and the case air flow sucks, literally everything thermal throttles in the case so i'm now relying on external cooler since there are only two case fan header on itx motherboads, so i'm starting with GPU. The GPU's problem got solved bu putting two 120mm mining case fans which took both of the case fan header on motherboard that's why i said noise is not a problem since those are alread extremely loud, now it's PSU and not it's CPU and PSU, the PSU was cooled by an external 1500rpm 120mm, and it's now to cool CPU, the CPU has a 92mm 2500rpm 12 bladed heatsink that's only rated 100W TDP, so i'm thinking of putting the same external fan onto the CPU, so would it help cooling get better?

cpu's fan's 40CFM btw
